10 Claims. (01. 250-34) This invention-relates to a film marker adapted to be used by X-ray specialists in the process of making X-ray pictures of parts of the human anatomy and other objects for photographically impressing upon the photographic plates or films any desired identification characters and serial number of each particular case together with such other information as may be required for future reference.

In the use of devices of this character it is important that all of the type shall be disposed in a flat plane substantially normal to the X-rays or at least parallel with and in close proximity to the supporting-plate upon or near which the object or objects including the type-plates are adapted to be supported during the photographing process.

One of the main objects, therefore, of the present invention is to provide a simple and comparatively inexpensive marker in which all of the type shall be held in fixed relation to each other and in substantially the same plane or in juxtaposed parallel planes so that the marker unit may be placed fiatwise upon or adjacent the 25 object supporting-plate to enable its reference characters of ray-impervious material to be photographically impressed upon the photographic plate or film simultaneously with the impression of the principal object.

30 In other words I have sought to provide a more economical means for supporting the individual type in proper position for photographic reproduction on the photographic plate or film than has heretofore been practiced and to enable the 35 individual type to be selected and arranged in such relation as may be desired as distinguished from the collective prearranging of the type either by stenciling or unitary combinations of the type.

Other objects and uses relating to specific parts 40 of the device will be brought out in the following description.

In the drawing:

Figure 1 is a perspective view of an X-ray marker embodying various features of my in- 45 vention.

Figure 2 is an enlarged longitudinal sectional view of the same taken in the plane of line 2-2, Figure 1.

Figure 3 is an enlarged transverse sectional view 50 taken in the plane of line 3- 3, Figure 1.

- Figure 4 is a perspective view of the detached holder for the type plates.

Figure 5 is a perspective view of the detached keeper plate for retaining the type plates flatwise 55 in the holder.

Figure 6 is a perspective view of the laminated type plate showing a portion of one of the layers broken away to reveal the type.

Figure '7 is a perspective view of one of the individual type sections. 5

Figure 8 is a face view of a photographic plate with the informative matter of the type plates reproduced thereon.

As illustrated this X-ray marker comprises a substantially rectangular holder l of ray-perme- 10 able material such as aluminum elongated in one direction and provided with a substantially fiat bottom portion back-plate 2 and opposite upright side portions 3 extending along the longitudinal edges of the bottom portion 2 and pro- 15 videdwith inturned lengthwise flanges 4 forming longitudinal grooves 5 which also extend along the longitudinal edges of the bottom plate as shown more clearly in Figure 4, the flanges 4 being relatively narrow to leave a clear open space between them and together with the grooves form a lengthwise guide for the type bearing sections presently described.

Associated with the holder l is a laminated rectangular type-bearing plate 6 of about the same length and width as the bottom 2 of the holder 9 and composed of relatively thin layers 1 and 0 of different ray-permeable material such for example as celluloid and fabric adhesively secured together face to face and adapted to receive between them opposite rows of type 9 and it! which are arranged adjacent the opposite lengthwise edges of the plate 8 in transversely spaced relation.

These type, 9 and 10, are preferably made in separate units of lead or other ray-impenetrable material, said units being arranged in sequence along the opposite lengthwise edges of and between the layers 1 and 8 and adhesively secured to the layer l or to both layers which serve to hold the type in fixed relation so that when the laminated plate 5 is inserted in the grooves 5 of the holder 1! the opposite rows of type 9 and 10 will underlie the fianges s, the row of type 9 indicating, in this instance, the doctor having the case in charge while the row of type It indicates the address of the doctor. I

When the laminated plate 5 is inserted in proper position in the holder 1 a flat slide or keeper plate ll of relatively thin ray-pervious material, such as aluminum, of slightly greater length than and of about the same transverse width as the bottom 2 of the holder i will be inserted endwise in the grooves 5 across the outer surface of the laminated plate 6 to hold the latter fiatwise in said holder against buckling and substantially parallel with the bottom 2.

The opposite ends I2 of the slide II projecting beyond the corresponding ends of the bottom 2 of the holder I will then be bent downwardly and longitudinally under the adjacent portions of said bottom to hold the slide and laminated plate 6 against endwise displacement from the holder. 7

After the laminated plates 6 and slide I I have been placed in operative position in the manner described additional type plate sections I3 of substantially the same width as the bottom 2 of the holder I are slidably inserted in sequence fromone end into the guide grooves 5 between the outer surface of the type plate 6 and flanges each section I 3 being provided with identification type of lead or equivalent ray-impervious material adhesively secured thereto substantially midway between the opposite longitudinal edges thereof so that when thesections are placed sequentially in different positions in the holder the type I4 will be outermost.

These identification type I4 may be letters or figures or a combination of letters and figures which, when photographically impressed upon the photographic plate as A, will be reproduced the same order or relation for identification of the case under the designated doctor's care.

The letters I4 on one or more of the type plate sections I3 may indicate the righthand or lefthand portion of the anatomy of the object operated upon while the remaining numbers I4 indicate the serial number of the particular case under treatment which in turn may, through other. records, identify the subject operated upon.

All of the type 9 and I0 and I4 are made of lead or equivalent material which is impenetrable by the X-rays used in the photographic process while all of the other parts of the device are pervious to the X-rays, the photographic reproduction of the type 9, I0 and It being indicated on the photographic plate or film A as 9', iii, and I4.

Operation The individual type 9 and ID are adhesively applied to one of the surfaces of the celluloid or equivalent layer 1 in the order shown in Figure 6, after which the fabric or equivalent layer 8 is adhesively applied to the same surface of the layer '1 and to the corresponding surface of the type 9 and Ill thus completing the type plate 6.

This type plate 6 is then inserted endwise into the grooves 5 of the holder I as shown more clearly in Figure 2 after which the slide II is placed in operative position in the grooves 5 and its ends bent down and under the corresponding ends of the bottom 2 to hold the laminated plate 6 against endwise displacement from the holder.

The type plate sections I3 with the type I4 thereon are then placed in operative position within the holder I in the order shown in Figure 1, thus bringing the type I4 in a line between the rows of type 9 and I 0, the slide II serving as a back support for the sections I3 to hold the latter in a substantially fiat plane.

It is now evident that when the type plate 6 bearing the name and address of the doctor having the case in charge is placed in operative position within the holder I it will be held in such position by the slide II and may remain in such position for further use with additional cases by the same doctor.

It will be noted, however, that the type bearing sections I3 with the type thereon are free ly slidable by hand in the grooves 5 of the holder I and may be changed for each new case by simply sliding the sections endwise from the holder and replacing them with other identification characters so that each case may be identified by its serial number while the letter type may serve to indicate to the attendant or physiclan the particular position, right or left, of the i0 anatomical part being treated.
